Abstract
The output delivered by a transducer having an integral power law transfer characteristic is stabilized by controlling output signal components related to the operating bias and gain of the transducer circuit. A test input signal comprising a sine-wave is applied to the transducer. The fundamental and integral harmonic components are filtered from the resulting output signal. The transducer is stabilized by restoring in sequence the amplitude of the harmonic and fundamental components to predetermined values respectively related to desired operating gain and bias conditions. A typical transducer is a cathode ray tube.
